There’s been talk about a “Sin City 2″ for years now, with the back and forth dialogue focusing on partially written scripts and delays. But at New York Comic Con, the creator of the comics and co-director Frank Miller told MTV Geek that he and Robert Rodriguez were polishing up the script to potentially begin production soon.”Robert Rodriguez and I are finishing up the script on ‘Sin City’ right now and could be shooting as early as this spring,” Miller says. His comments line up with what Rodriguez said earlier this year.Miller also went into detail about which stories from the universe would factor into the sequel. “‘Sin City 2′ is primarily an adaptation of the book ‘A Dame to Kill For,’” Miller says. “It also features the short story, ‘Just Another Saturday Night,’ and two new stories, one involving Jessica Alba’s character of Nancy Callahan that I came up with for the movie, in order to tie things together and make it be more united with the first.”But Miller wants to make sure he doesn’t reveal everything about the potential sequel just yet. “That’s about all I can tell you about the story right now because these things are always in flux, and I don’t want to be one of those embarrassing people who says the wrong thing and it lasts forever on the internet,” Miller says.See MTV Geek for more on the “Sin City” sequel, and stay with MTV News and Splash Page for the latest news on the project.
